What do I need to know in order to show my chickens?

I have a few chickens that I think are good definitions of the breed. I would like to show them next year in the fairs. Can you guys give me some advice on the things I need to be doing with my birds now while they are still little. I want them to be used to the handeling etc. early on. My daughter is also doing 4H so she will need to learn these things as well. Thanks in advance.
